Here I try to describe my needs more detailed: On other side of PPP interface (4) I'll have two clients, 4.1 and 4.2 I'll have the following data flows in my system (sorted by priority) 1. Internet via (1) <-> 3; (highest priority) 2. 3 <-> 4.1; 3. Internet via (1) <-> 4.2; 4. Internet via (1) <-> 2; I need to make rules like: if we have packet from 3 to Internet, all other will wait; If we have packet from 3 to 4.1 via PPP, other PPP traffic (to 4.2) will wait. etc I suppose that the hardest part will be to regulate incoming traffic from 1. On opposite side of 2,4 I plan to setup FreeBSD routers with ALTQ - this should help me.
